Banished is a very fun little city builder, but it is a little limited in scope. It could really have stood to have tech levels or something similar, to let you build things up taller as well as broader.

That said, there are mods like Colonial Charter that more or less totally address this point, so it's hard to care too much.

Also, been replaying Suikoden the last couple of days, and aside from the UI jank you can expect from a mid-90s RPG, the one thing I would really like to have seen is bonus endgame content, bonus dungeons and bosses and stuff.
